Specification of Letters Patent,

Patented Nov. 19, 1007.

Application filed July 26, 1906. Serial No. 327.880.

To all whom it may concern:

Be it known that we, ERNEST A. OAKES and PETER A. CooNEY, citizens of the United States, residing at Chicago, in the county of COOlL ind State of Illinois, have invented certain new and useful Improvements in Recorders, of which the following is a specification.

It is often desirable in a factory or other institution, for various reasons, to have a record of the exact number of hours each piece of apparatus, machine tool, or other machine in the factory is in operation during each day, the length of time each machine is idle, and the time of day when the operation of any machine is started and stopped.

This invention refers to, an automatic mechanism for producing such. a record. As will be mnlerstood from the accompanying drawings and description, the various machines are electrically connected with the recording mechanism, and the starting and stopping or each machine is duly registered upon a properly ruled sheet spread upon the recorder drum.

in the accompanying drawings, Figure .l a front or 'tion, ,artly in section, of a re cordcr en'ibr jing t e features of our invention. l ig. 2 is an end elevation of said rocorder. F is :rfragmental detail view of the escape: t mechanism. Fig. is a diagram ll icing the manner in which the recorder is JllilQOlKl with one of the machines whose operation it is (h; ircd to record. 5 is a derail sectional View through the series oi clortro-inagncts.

The embodiment herein shown of our inilrznne 1 formed or the base 3 and the side members 5% and Amos :3 projecting forward mardly from sziid side members are connectod by .two bars 6 and 7, to each oi which bars if: secured :1 plurality of horseshoe electromagnets 8 and .{L The clertromagnets S are arranged with their poles extending up- Wardly and. the row of eleriromagncts 9 with their poles extending downwardly. Upon a fixed shaft l extending between the arms is pivoini nipported a number of bell-crank levers ii, one for each of the elnctroiinignets S and 9. One arm 12 of each of said bellcrank levers has attached thereto an armature 13 and the other arm 14 is provided at its lower end with a suitable marking dexdce Fig.

to hear u on the eriphery of a o lindrical drum to he later erein describe and are normally held out of contact with said drum by means of coiled springs 16 extending between the lever-arms 14 and the bar 6.

It will be noted that the two coils constituting each electromagnet are-arranged one behind the other for the sake of compactness in arrangement, and that the two series of electromagnets 8 and 9 are located out of alinement with each other so that the bellcrank levers 11 for both series of electroinagnets may be supported upon the same shaft.

Upon a shaft 17 rotatebly supported in v the side members 3 and 4 is loosely mounted a cylinder 18 supported upon said shaft by means of the hubs l9 and the spoke-arms 20, said hubs being rigidly mounted upon a sleeve 21 surrounding the shaft 17.. The cylinder 18 is provided with any suitable means (not herein shown) for securing a sheet of paper upon its periphery, upon which sheet the marking devices are arranged to bear. For rotating the cylinder 18 we provide a coiled (clock) spring 22, the inner end of which ring is attached to a spring barrel. 2Z5 ii'mtably mounted upon the shait 17, the outer end oi said spring being lined in a pin ii suppm'ird in the end member 3 and a bucket 25 lixed to said end member. Upon the spring barrel 33 are fixed two ratchcls so and 27, one at each side of the spring 212, The teeth of the ratchet wheel 36 are adapted to be engaged by a pawl 28 carried by a winding crank 29 rotatably mounted upon the shaft 17. V Durin the operation of the. recorder the pawl 25 is held out oi engagement with it's ratchet wheel 26. An arm 30 is rigidly inounled upon the shaft l7 adjacent to the ratchet wheel 2!, said. arm carryin' a pawl 7L adapted to engage the teeth of said ratchet wheel. 7

One end oi the sleeve ll upon which the cylinder in mounted pi jects be adjacc i hub 19, id

pin Upon il e iothe pin 0 s a clutch collar SS'hnYing n nolch 34 in one of its is adapted to receive the pin said collar icing splint-d to said shaft and therefore rota blc with the shaft :is well ns longitudinally slidnhlc upon it. in one end ol the collar 33 is :1 peripheral groo 35 adapted to receive studs '36 upon the forked upper endjof a clutch. lever Said lever is pivotally supported upon a stud 38 projecting from the side member 4, and affords means for sliding the clutch collar 33 longitudinally on the shaft 17 toengage and disengage said collar and the pin 32.

The rotation of the shaft 17 is controlled by means of an escapement mechanism 39 of any common or preferred form. Said mechanism is supportedvupon arms 40 and 41 formed upon the side member 4.

Each of the electromagnets 8 and 9 is included in an electrical circuit with a circuitopening and closing device arranged to be actuated by the apparatus, machine or mechamsm whose time of operation is to be recorded, the circuit being arranged-to be closed when the machine is placed in operation and opened whenv .the machine is stopped. The precise manner of actuating the circuit-opening and closing device will depend, of course, upon the characterof the particular machine or apparatus, but in most cases the device will be arranged to be actuated by the operation of the startin and stopping mechanismof the machine. ig. 4 is a diagrammatic illustration of one method of including the starting and stopping mechanism of a machine in the recorder circuit. '42 is a lever for operating the reversing clutch of a machine. Said lever carries two contact blades 43 and 44, the blades 43 being adapted to enter between two spring blades and 46, and the blade 44 being ada ted to lie between two spring blades 47 an 48. The blades 45 and 47 are electricallyconnected with one end of the winding of the electromagnet, and the blades 46 and 48. with the opposite end of the winding.

49 is a battery or other suitable source of electrical energy.

Ifdesired the recorder may be inclosed within a suitable casing (not herein shown), which casing may be provided with glasscovered sight openings through which the operation of the marking devices and the rec{ 0rd made by them may be observed.

In practice, each machine, apparatus, or mechanism in the factory, whose operation it is desired to record, is electrically connected with one of the electromagnets 8 and 9 of the recorder in such a wa that a circuit will be closed through the e ectromagnet when the machine is placed in operation, and so that thecircuit will be opened when the operation of the machine iceas'es. The cylinder 18 is provided upon its eriphery with a blank sheet or chart suitab y ruled and inscribed to indicate the twelve workin hours of a day or any desired portion thereog The coiled spring 22 is wound up by a succession of partial rotations of the crank 29, and the escapement ,mechanism started, thus rotating the cylinder. The marking devices 15 are normally held out of contact with the chart upon the cylinder "18 by means of'the coiled springs 16', but when one of the machines connected with the recorder is placed in operation an electric circuit is closed through one; of the electromagnets, and the armature 13 for said electromagnetattracted, thereby throwing the marking device associated with said electromagnet into contact with the chart upon the cylinder 18.

The marking device 15 is thusheld in contact'with the chart so-long as the machine is in, operation. The cylinder 18 meanwhile rotates and the marking device traces a line upon the chart. The latter having been placed upon the cylinder 18 so as to bring the time division of said chart corresponding with the time of day that the recorder'was started directly beneath the row of marking devices 15, it will be seen that the line traced by an actuated marking device will begin at a a time division on the chart corresponding with the time of day when the machine was placed in operation, and will endwhen the machine is sto ped,'the-circuit opened, and the marking evice raisedffrom the paper. A'record is thusobtained'of the time of day when each machine in the factory is placed in operation and stopped, the length of time the machine is used, and the intervals, if any, during which the :machine Was idle.

When the record sheet is to be removed, the cylinder 18 is unclutched from the shaft 17, thesheet removed and a new sheet substituted therefor, said new sheet occupying the-same position upon the cylinder as the former sheet did, the cylinder 18 manually rotated onward to the extent that. the shaft 17 has rotated in the meantime, and said cylinder connected with the shaft by means of the clutch 32 33.1 V

We are aware'that various changes can be made in the construction and arrangement.

of the parts and circuits of the apparatus herein shown and described. Said embodiment is largely illustrative, and 'is capable of modification to adapt it to use with various t t erefore desire to have it understood that we do not limit ourselves 'to' the precise details herein shown and described.
